AN EARLIER THREAD FOR CENTERBOARD PROBLEMS WITH THE M17, TALKED ABOUT REMOVING THE CENTERBOARD AND ADDING A WINGED KEEL. HAS ANYONE TRIED THIS IDEA? ALSO - ANYONE MAKE A DODGER FOR THE M17? THANKS Lon SELKIE ============ ============ ========== [Dick Straubel Sat, 20 Sep 2008 08:06:11 -0700] Would increase the draft by the thickness of the metal plate. When heeled, the wing might go down deeper as it tilts, but not significant and would not increase draft more than the thickness of the plate when not heeled. The plate could actually be quite thin, and weight or original board could be replaced by pouring a lead/resin gruel down into the trunk from above. The trick would be to design the rake of the wing blades and determine the position of the wing plate fore and aft on the keel to achieve the best helm balance. I believe the point of raking/sweeping the wings is to adjust the center of lateral resistance aft as the boat heels so the helms stays close to balanced
